You can use words like epic, haunting and intense, but it was delicate, soft and intimate as well.

Drawing the set — which was admittedly rather brief considering the £26.50 ticket price — from 2009's self-titled debut album and last year's follow-up, Coexist, the Jools Holland-approved Mercury Prize-winners captivated the audience.

The brooding music was complemented by the threesome's attire, uniformly black, while a rhythmic laser show pulsated around them.

As much effort seemed to have gone into the presentation as the music, and whether that's a good or bad thing is a matter of opinion.

But it appeared to be a rare case of style and substance being present in equal measure. And often, it was the spaces between the sounds that made the most impact — what the xx weren't playing rather than what they were. Simply a masterful manipulation of mood.
